Description

Technical Field

[0001] This invention relates to hair care compositions comprising odor-reducing compositions and methods for preparing and using such hair care compositions. Background Technology

[0002] Fragrance-free or mildly scented products are desirable to consumers because they are perceived as more natural and less noticeable compared to strongly scented products. Manufacturers of fragrance-free or mildly scented products for odor control rely on odor-reducing ingredients or other technologies (e.g., filtration) to reduce odors. However, effectively controlling odors (e.g., amine-based odors (e.g., fish and urine), thiol- and sulfide-based odors (e.g., garlic and onion), and C2-C-based odors) is crucial. 12 The odors associated with carboxylic acids (such as body odor and pet odor), indole-based odors (such as fecal and halitosis), short-chain fatty aldehyde-based odors (such as oils and fats), and earth element-based odors (such as mold / fungus) can be difficult to mask, and the time required for a product to significantly reduce odors may cause consumers to doubt its effectiveness. Often, manufacturers add scented fragrances to help mask these unbearable odors.

[0003] Unfortunately, odor control technologies often mask odors with stronger fragrances, thus interfering with the odor of scented or unscented areas treated with the technology. Therefore, the limitations of current odor control technologies are extremely restrictive. What is needed, therefore, is a wider range of odor control technologies that allow fragrance compounds to deliver the desired level of properties in a greater variety of situations / applications. Surprisingly, the applicant recognized that, in order to achieve the desired goal, odor control technologies must not only block odors from reaching receptor cells, but also open these receptor cells to other molecules, such as fragrance molecules. Therefore, hair care compositions incorporating the odor control technologies disclosed herein provide odor control without leaving an undesirable fragrance, and when fragrances are used to enhance the scent of such compositions, this fragrance is not excessively altered by the odor control technology.

[0004] Sulfur-based antifungal hair and scalp care compositions offer some of the most effective protection and relief for dandruff conditions. Historically, sulfur and other sulfur-based preparations have had a strong medicinal and irritating odor during use and throughout the day, due to residual sulfur compounds depositing on the hair and scalp and their interactions with the hair and skin. These significantly negative cosmetic properties may have led consumers to avoid sulfur and other sulfur-based preparations, making product compliance difficult and resulting in consumers finding their dandruff conditions often not fully relieved. Summary of the Invention

[0005] The present invention relates to a hair care composition comprising, based on the total weight of the composition, a) a total amount of about 0.1% to about 2% of a fragrance having one or more odor-reducing materials, having about 0.0001% to about 2% by weight of one or more of the odor-reducing materials; b) about 0.01% to about 10% of a scalp active substance selected from the group consisting of sulfur and mixtures thereof; and c) about 0.1% to about 40% of a surfactant. Detailed Implementation

[0006] definition

[0007] The term "hair care composition" as defined herein may include shampoos, conditioners, and leave-in treatments.

[0008] "Wash-off" refers to products intended for application to hair, followed by washing and / or wiping off the skin and / or hair within seconds to minutes of application.

[0009] "STnS" refers to sodium tridecyl polyoxyethylene ether (n) sulfate, where n can define the average number of moles of ethoxylate per molecule.

[0010] As used herein, “MORV” is the calculated odor reduction value of the material under discussion. The MORV of a material represents its ability to reduce or even eliminate the perception of one or more odors. For the purposes of this patent application, the MORV of the material is calculated according to the methods described in the Test Methods section of this patent application.

[0011] As used in this article, "foul odor" refers to compounds that are generally disliked or unpleasant to most people, such as complex odors associated with intestinal motility.

[0012] As used in this article, "odor blocking" refers to the ability of a compound to reduce the perception of foul odors.

[0013] As used herein, the term "fragrance" does not include odor-reducing materials. Therefore, when determining the composition of a fragrance, the fragrance portion of the composition does not include any odor-reducing materials present in the composition, such as those described herein. In short, a material is an odor-reducing material for the purposes of such claims if it has an odor reduction value "MORV" within the MORV range described in the subject matter claims.

[0014] As used in this article, PRM is an abbreviation for Flavoring Raw Materials.

[0015] As used herein, the terms “an” and “a kind” mean “at least one / kind”.

[0016] As used herein, the terms “including,” “comprising,” and “containing” are intended to be non-restrictive.

[0017] Unless otherwise specified, all component or composition levels refer to the active portion of the component or composition and do not include impurities, such as residual solvents or byproducts, that may be present in commercially available sources of such components or compositions.

[0018] Unless otherwise specified, all percentages and ratios are by weight. Unless otherwise specified, all percentages and ratios are based on the total composition.

[0019] It should be understood that each maximum numerical limit given in this specification includes each lower numerical limit, as such lower numerical limits are explicitly stated herein. Each minimum numerical limit given in this specification will include each higher numerical limit, as such higher numerical limits are explicitly stated herein. Each numerical range given in this specification will include each narrower numerical range falling within such a wider numerical range, as all such narrower numerical ranges are explicitly stated herein.

[0020] Hair care composition

[0021] Wash-off hair care compositions can be in various forms. For example, hair care compositions can be in liquid form and can be shampoos or conditioning shampoos.

[0022] Hair care compositions may include fragrance materials. Many consumers prefer hair care compositions that consistently provide a desired scent or that allow the user to experience the aroma every time they use the product. Fragrance materials provide these hair care compositions with a desired fragrance or odor. These fragrance (i.e., aromatizing) materials may include fragrances, fragrance ingredients, and fragrance delivery systems. The present invention may contain a total amount of about 0.1% to about 2% of fragrances having one or more odor-reducing materials; may contain a total amount of about 0.5% to about 1.5% of fragrances having one or more odor-reducing materials; may contain a total amount of about 0.8% to about 1.2% of fragrances having one or more odor-reducing materials; may contain a total amount of about 0.85% to about 1.0% of fragrances having one or more odor-reducing materials.

[0045] sulfur

[0046] The hair care compositions of the present invention may contain sulfur. Sulfur as used herein can be any form of elemental sulfur. Sulfur exists primarily as orthorhombic crystals at room temperature. The two most common ways to obtain elemental sulfur are: precipitation from hydrogen sulfide, one route being from acid gas contamination via the Claus process, and collection of underground sediments using superheated water (known as the Frasch process). Other forms of sulfur, such as monoclinic crystalline sulfur, oligomeric or polymeric sulfur, are the normal primary forms of elemental sulfur at certain higher temperature ranges. At room temperature, these forms convert or reverse to orthorhombic sulfur. Sulfur in elemental form can be sulfur that has been physically mixed with protective colloids such as gum arabic, clay, wax, oil, activated carbon, zeolite, silica, or dispersants such as surfactants, or has undergone processing steps to alter its particle size or other physical properties. Sulfur is commercially available in various forms such as pellets, cakes, spheres, colloids, micronized, sublimated, precipitated, and commercial powders.

[0047] Sulfur may have a particle size distribution in which 90% of the particles (D90) are from about 30 micrometers (μm) to about 250 micrometers (μm); sulfur may have a particle size distribution in which D90 is from about 30 micrometers (μm) to about 200 micrometers (μm); sulfur may have a particle size distribution in which D90 is from about 30 micrometers (μm) to about 150 micrometers (μm); sulfur may have a particle size distribution in which D90 is from about 30 micrometers (μm) to about 100 micrometers (μm).

[0048] Sulfur may have a particle size distribution in which 50% of the particles (D50) are from about 5 micrometers (μm) to about 150 micrometers (μm); sulfur may have a particle size distribution in which D50 is from about 10 micrometers (μm) to about 100 micrometers (μm); sulfur may have a particle size distribution in which D50 is from about 15 micrometers (μm) to about 75 micrometers (μm); sulfur may have a particle size distribution in which D50 is from about 20 micrometers (μm) to about 50 micrometers (μm).

[0049] Sulfur may have a particle size distribution in which 10% of the particles (D10) are from about 1 micrometer (μm) to about 25 micrometers (μm); sulfur may have a particle size distribution in which D10 is from about 5 micrometers (μm) to about 25 micrometers (μm); sulfur may have a particle size distribution in which D10 is from about 10 micrometers (μm) to about 25 micrometers (μm); sulfur may have a particle size distribution in which D10 is from about 18 micrometers (μm) to about 25 micrometers (μm).

[0050] Sulfur can exist in a D(90) / D(10) ratio of about 3 to about 100; sulfur can exist in a D(90) / D(10) ratio of about 3 to about 50; sulfur can exist in a D(90) / D(10) ratio of about 3 to about 10; sulfur can exist in a D(90) / D(10) ratio of about 3 to about 4.

[0051] Sulfur may be present in amounts of about 0.01% to 10%, about 0.1% to about 9%, about 0.25% to 8%, and about 0.5% to 6%.

[0052] Additive materials

[0053] While not essential for the purposes of this invention, the non-limiting list of adjuvants described below applies to ready-made compositions and may be advantageously incorporated into certain aspects of the invention, for example, to aid or enhance performance.

[0054] A variety of optional ingredients can also be added to hair care compositions. Optional ingredients may include, but are not limited to, structuring agents, humectants, fatty acids, inorganic salts, and other antimicrobial agents or active substances.

[0055] Hair care compositions may also contain hydrophilic structural agents such as carbohydrate structural agents and gums. Some suitable carbohydrate structural agents include raw starch (corn, rice, potato, wheat, etc.) and pregelatinized starch. Some suitable gums include carrageenan and xanthan gum. Hair care compositions may contain about 0.1% to about 30%, about 2% to about 25%, or 4% to about 20% of carbohydrate structural agents by weight of the hair care composition.

[0056] Hair care compositions may also contain one or more humectants. Examples of such humectants may include polyols. Furthermore, humectants such as glycerin may be included in the hair care composition as a preparation process or as an additional ingredient. For example, glycerin may be a byproduct of the saponification of the hair care composition. Including additional humectants can result in a number of beneficial effects, such as improving the stiffness of the hair care composition, reducing the water activity of the hair care composition, and reducing the rate of weight loss of the hair care composition over time due to water evaporation.

[0057] Hair care compositions may contain inorganic salts. Inorganic salts can help maintain a specific water content or level in the hair care composition and improve the stiffness of the hair care composition. Inorganic salts can also help bind water in the hair care composition to prevent water loss due to evaporation or other means. Hair care compositions may optionally contain about 0.01% to about 15%, about 1% to about 12%, or about 2.5% to about 10.5% of inorganic salts by weight of the hair care composition. Examples of suitable inorganic salts may include magnesium nitrate, trimagnesium phosphate, calcium chloride, sodium carbonate, sodium aluminum sulfate, disodium phosphate, sodium polymetaphosphate, sodium magnesium succinate, sodium tripolyphosphate, aluminum sulfate, aluminum chloride, hydrated aluminum chloride, hydrated zirconium aluminum trichloride, hydrated zirconium aluminum trichloride glycine complex, zinc sulfate, ammonium chloride, ammonium phosphate, calcium acetate, calcium nitrate, calcium phosphate, calcium sulfate, ferric sulfate, magnesium chloride, magnesium sulfate, and tetrasodium pyrophosphate.

[0058] Hair care compositions may contain one or more additional antimicrobial agents that may be used to further enhance the antimicrobial efficacy of the hair care composition. For example, a hair care composition may contain about 0.001% to about 2%, about 0.01% to about 1.5%, or about 0.1% to about 1% of an additional antimicrobial agent by weight of the hair care composition. Examples of suitable antimicrobial agents include carbamate, triclocarban (also known as trichlorocarbamate), triclosan, halodiphenyl ethers available from Ciba-Geigy under the trade name DP-300, hexachlorophenol, 3,4,5-tribromosalicylic acid aniline, and salts of 2-pyridinium-1-oxide, salicylic acid, and other organic acids. Other suitable antimicrobial agents are described in U.S. Patent No. 6,488,943.

[0059] Scalp active substances

[0060] The hair care composition of this invention may contain a scalp-active substance, which may be an anti-dandruff active substance. The anti-dandruff active substance may be selected from: pyrithione salts; zinc carbonate; azoles, such as ketoconazole, econazole, and neoconazole; selenium sulfide; particulate sulfur; colloidal sulfur; keratin-removing agents, such as salicylic acid; and mixtures thereof. The anti-dandruff active substance may be anti-dandruff microparticles. Anti-dandruff microparticles may be pyrithione salts. Such anti-dandruff microparticles should be physically and chemically compatible with the components of the composition and should not unduly otherwise impair the stability, aesthetics, or performance of the product.

[0061] In this invention, sulfur or selenium sulfide may be present in amounts of about 0.01% to 10%, about 0.1% to about 9%, about 0.25% to 8%, and about 0.5% to 6%.

[0062] Pyridinethione microparticles are granular anti-dandruff active ingredients suitable for use in the compositions of the present invention. In the present invention, the anti-dandruff active ingredient may be a 1-hydroxy-2-pyridinethione salt and is in microparticle form. In the present invention, the concentration of the pyridinethione anti-dandruff microparticles may range from about 0.01% to about 5%, or about 0.1% to about 3%, or about 0.1% to about 2% by weight of the composition. In the present invention, the pyridinethione salt may be those formed from heavy metals such as zinc, tin, cadmium, magnesium, aluminum, and zirconium (usually zinc), typically a zinc salt of 1-hydroxy-2-pyridinethione (referred to as "zinc pyridinethione" or "ZPT"; zinc pyridinethione), typically in the form of flaky particles. In the present invention, the 1-hydroxy-2-pyridinethione salt may be in the form of flaky particles with an average particle size of up to about 20 micrometers, or up to about 5 micrometers, or up to about 2.5 micrometers. Salts formed from other cations such as sodium are also suitable. Pyrithione anti-dandruff active ingredients are described, for example, in U.S. Patents 2,809,971, 3,236,733, 3,753,196, 3,761,418, 4,345,080, 4,323,683, 4,379,753, and 4,470,982.

[0063] In this invention, in addition to anti-dandruff active substances selected from polyvalent metal salts of pyridinethione, the composition may also contain one or more antifungal and / or antimicrobial active substances. In this invention, the antimicrobial active substance may be selected from the group consisting of: coal tar, sulfur, charcoal, compound benzoic acid ointment, castarin, aluminum chloride, gentian violet, oxymethopyrone (pyrrolidone ethanolamine salt), ciclopiroxamine, undecanoic acid and its metal salt, potassium permanganate, selenium sulfide, sodium thiosulfate, propylene glycol, bitter orange oil, urea preparations, azoxystrobin, griseofulvin, 8-hydroxyquinoline chloroquine, thiodibazol, thiocarbamate, halopramidine, polyene, hydroxypyridinium, morpholine, benzylamine, allylamine (such as terbinafine), tea tree oil, clove leaf oil, coriander, palmarosa, berberine, thyme, cinnamon oil, cinnamaldehyde, citronellolic acid, physalisol, shale oil, Sensiva SC-50, Elestab. HP-100, azelaic acid, lysozyme, iodopropynyl butylcarbamate (IPBC), isothiazolinones such as octylisothiazolinone and azoles, and mixtures thereof. In this invention, the antimicrobial agent may be selected from the group consisting of itraconazole, ketoconazole, selenium sulfide, coal tar, and mixtures thereof.

[0064] In this invention, the azole antimicrobial agent may be an imidazole selected from: benzimidazole, benzothiazole, bifonazole, buconazole nitrate, clotrimazole, clotrimazole, kluconazole, epconazole, econazole, neoconazole, fenteconazole, fluconazole, flutriazole, isoconazole, ketoconazole, lanoconazole, metronidazole, miconazole, neconazole, omeconazole, oxiconazole nitrate, sertaconazole, thioconazole nitrate, thiaconazole, thiazole, and mixtures thereof; or the azole antimicrobial agent may be a triazole selected from: terconazole, itraconazole, and mixtures thereof. When present in the composition, the azole antimicrobial agent is included in an amount of about 0.01% to about 5%, or about 0.1% to about 3%, or about 0.3% to about 2% by weight of the composition. In this invention, the azole antimicrobial active substance may be ketoconazole. In this invention, the sole antimicrobial active substance may be ketoconazole.

[0065] The present invention may also comprise a combination of antimicrobial active substances. In the present invention, the combination of antimicrobial active substances may be selected from the group consisting of: oxymethopyrone and zinc pyrithione, pine tar and sulfur, salicylic acid and zinc pyrithione, salicylic acid and neoconazole, zinc pyrithione and neoconazole, zinc pyrithione and imidacloprid, oxymethopyrone and imidacloprid, salicylic acid and oxymethopyrone, and mixtures thereof.

[0066] In this invention, the composition may contain an effective amount of zinc-containing layered material. In this invention, the composition may contain about 0.001% to about 10%, or about 0.01% to about 7%, or about 0.1% to about 5% of zinc-containing layered material based on the total weight of the composition.

[0067] Zinc-containing layered materials can be those that exhibit crystal growth primarily in a two-dimensional plane. Layered structures are conventionally described as those in which not only all atoms are incorporated into well-defined layers, but also in which ions or molecules known as tunneling ions exist between the layers (AF Wells, "Structural Inorganic Chemistry," Clarendon Press, 1975). Zinc-containing layered materials (ZLMs) may have zinc incorporated into the layers and / or components that can act as tunneling ions. The following categories of ZLMs represent relatively common examples within the overall category and are not intended to limit the scope to a wider range of materials conforming to this definition.

[0068] Many zinc tunneling metals (ZLMs) occur in nature as minerals. In this invention, ZLMs may be selected from: zinc hydrate (zinc carbonate hydroxide), basic zinc carbonate, zinc chalcopyrite (zinc carbonate copper hydroxide), orthorhombic zinc chalcopyrite (copper carbonate zinc hydroxide), and mixtures thereof. Related zinc-containing minerals may also be included in the composition. Natural ZLMs may also be present, wherein anionic layer materials such as clay-type minerals (e.g., shale silicates) contain ion-exchanged zinc tunneling ions. All these natural substances may also be obtained synthetically, or formed in situ in the composition or during the production process.

[0069] Another common class of ZLMs, typically but not always synthesized, is layered binary hydroxides. In this invention, ZLMs may conform to the formula [M 2+ 1-x M 3+ x (OH)2] x+ A m- x / m Layered binary hydroxides of nH₂O, some or all of which contain divalent ions (M 2+ (Crepaldi, EL, Pava, PC, Tronto, J, Valim, JB J. Colloid Interfac. Sci. 2002, 248, 429-42).

[0070] Another class of ZLMs, known as hydroxy complex salts, can be prepared (Morioka, H., Tagaya, H., Karasu, M, Kadokawa, J, Chiba, K. Inorg. Chem. 1999, 38, 4211-6). In this invention, the ZLM can be conforming to the formula [M2+ 1-x M 2 + 1+x (OH) 3(1-y) ] + A n- (1＝3y) / n ·nH2O hydroxy complex salt, in which two metal ions (M 2+ The ) can be the same or different. If they are the same and represented by zinc, the formula simplifies to [Zn] 1+x (OH)2] 2x+ 2x A - ·nH₂O. The latter formula represents (where x = 0.4) materials such as zinc hydroxychloride and basic zinc nitrate. In this invention, ZLM can be zinc hydroxychloride and / or zinc hydroxynitrate. These also relate to zinc brine, where divalent anions replace monovalent anions. These materials can also be formed in situ in the composition or during or after the production process.

[0071] In this invention, the composition may comprise basic zinc carbonate. Commercially available sources of basic zinc carbonate include zinc carbonate basics (Cater Chemicals: Bensenville, IL, USA), zinc carbonate (Shepherd Chemicals: Norwood, OH, USA), zinc carbonate (CPS Union Corp.: New York, NY, USA), zinc carbonate (Elementis Pigments: Durham, UK), and zinc carbonate AC (Bruggemann Chemical: Newtown Square, PA, USA). Basic zinc carbonate, also commercially referred to as "zinc carbonate," "zinc carbonate basics," or "hydroxyzinc carbonate," is a synthetic form composed of materials similar to naturally occurring zincite. The ideal stoichiometry is Zn₅(OH)₆(CO₃)₂, but actual stoichiometry may vary slightly, and other impurities may be present in the crystal lattice.

[0072] The present invention may contain a zinc-containing layered material and a pyridinethione or a pyridinethione polyvalent metal salt, wherein the ratio of the zinc-containing layered material to the pyridinethione or pyridinethione polyvalent metal salt is about 5:100 to about 10:1, or about 2:10 to about 5:1, or about 1:2 to about 3:1.

[0073] Hair care composition

[0074] Exemplary hair care wash-off hair care compositions may include an aqueous carrier, which may be present at a level of about 5% to about 95%, or about 60% to about 85%. The aqueous carrier may include water or a miscible mixture of water and an organic solvent. Non-aqueous carrier materials may also be used.

[0075] In this invention, the surfactant may be present in the range of about 0.1% to about 40%, about 0.5% to about 30%, or about 1% to about 25%.

[0076] Such wash-off hair care compositions may contain one or more detergency surfactants. The detergency surfactant component may be included to provide cleaning properties to the product. The detergency surfactant component subsequently includes anionic, amphoteric, or amphoteric detergency surfactants, or combinations thereof. A representative non-limiting list of anionic surfactants includes anionic detergency surfactants used in the composition, which may include ammonium lauryl sulfate, ammonium lauryl polyoxyethylene ether sulfate, triethylamine lauryl sulfate, triethylamine lauryl polyoxyethylene ether sulfate, triethanolamine lauryl sulfate, triethanolamine lauryl polyoxyethylene ether sulfate, monoethanolamine lauryl sulfate, monoethanolamine lauryl polyoxyethylene ether sulfate, diethanolamine lauryl sulfate, diethanolamine lauryl polyoxyethylene ether sulfate, sodium monolaurate sulfate, sodium lauryl sulfate. Sodium lauryl polyoxyethylene ether sulfate, potassium lauryl sulfate, potassium lauryl polyoxyethylene ether sulfate, sodium lauryl sarcosinate, sodium lauroyl sarcosinate, lauryl sarcosinate, cocoyl sarcosinate, ammonium cocoyl sulfate, ammonium lauroyl sulfate, sodium cocoyl sulfate, sodium lauroyl sulfate, potassium cocoyl sulfate, potassium lauryl sulfate, triethanolamine lauryl sulfate, triethanolamine lauryl sulfate, monoethanolamine cocoyl sulfate, monoethanolamine lauryl sulfate, sodium tridecylbenzenesulfonate, sodium dodecylbenzenesulfonate, sodium cocoyl hydroxyethyl sulfonate, and combinations thereof. In one example, the anionic surfactant may be sodium lauryl sulfate or sodium lauryl polyoxyethylene ether sulfate. The concentration of the anionic surfactant component in the product is sufficient to provide the desired cleaning and / or foaming properties, and is typically in the range of about 2% to about 40%.

[0077] Amphoteric detergency surfactants suitable for wash-off hair care compositions are well known in the art and include those surfactants broadly described as derivatives of aliphatic secondary and tertiary amines, wherein the aliphatic group may be linear or branched, and wherein the aliphatic substituent may contain about 8 to about 18 carbon atoms, such that one carbon atom may contain a water-soluble anionic group, such as a carboxyl group, sulfonate group, sulfate group, phosphate group, or phosphonate group. Examples of compounds falling under this definition include sodium 3-dodecylaminopropionate, sodium 3-dodecylaminopropanesulfonate, sodium lauryl sarcosinate, N-alkyl taurine (such as that prepared by reacting dodecylamine with sodium hydroxyethyl sulfonate according to the teachings of U.S. Patent 2,658,072), N-higher alkyl aspartic acid (such as those prepared according to the teachings of U.S. Patent 2,438,091), and the product described in U.S. Patent 2,528,378. Other examples of amphoteric surfactants may include sodium lauroylamphoacetate, sodium cocoamphoacetate, disodium lauroylamphoacetate, disodium cocoamphoacetate, and mixtures thereof. Amphoteric acetates and diamphoacetic acetates may also be used.

[0078] Amphoteric surfactants suitable for wash-off hair care compositions are well known in the art and include those surfactants broadly described as derivatives of aliphatic quaternary ammonium, phosphonium, and sulfonium compounds, wherein the aliphatic group may be linear or branched, and wherein the aliphatic substituent may contain about 8 to about 18 carbon atoms, such that one carbon atom may contain an anionic group, such as a carboxyl, sulfonate, sulfate, phosphate, or phosphonate group. Other amphoteric surfactants may include betaines, including cocoaminopropyl betaine.

[0079] In this invention, the hair care composition may contain a cationic surfactant.

[0080] Liquid wash-out hair care compositions may comprise one or more phases. Such hair care compositions may comprise a cleansing phase and / or a beneficial phase (i.e., a monophase or multiphase composition). Each of the cleansing or beneficial phases may comprise multiple components. The cleansing and beneficial phases may be blended, separated, or a combination thereof. The cleansing and beneficial phases may also be patterned (e.g., striped).

[0081] The cleansing phase of a hair care composition may contain at least one surfactant. The cleansing phase may be an aqueous structured surfactant phase and may comprise from about 5% to about 20% by weight of the hair care composition.

[0102] Test method for determining saturated vapor pressure (VP at 25°C)

[0103] Calculate the saturated vapor pressure (VP) of each flavor ingredient (PRM) in the tested flavor blends.

(ACD / Labs) (Toronto, Canada), to provide VP values ​​at 25°C, expressed in Torr. The ACD / Labs vapor pressure model is part of the ACD / Labs Model Suite.

[0104] Test method for determining the logarithm of the octanol / water partition coefficient (ClogP)

[0105] The logarithmic value (logP) of the octanol / water partition coefficient for each PRM in the tested spice blend was calculated. The ClogP of individual PRMs was calculated using Consensus logP Computational Model version 14.02 (Linux), purchased from Advanced Chemistry Development Inc. (ACD / Labs) (Toronto, Canada), to provide dimensionless logP values. The Consensus logP Computational Model from ACD / Labs is part of the ACD / Labs Model Suite.

[0106] Test methods for generating molecular descriptors

[0107] To perform the calculations involved in the calculated value test method described herein, the required starting information includes the identifier, weight percentage, and molar percentage of each PRM in the flavoring being tested, as part of the flavoring composition, wherein all PRMs in the flavoring composition are included in the calculations. Additionally, for each of the PRMs, the molecular structure and values ​​of various calculated molecular descriptors are also required, as determined by the test method for generating molecular descriptors described herein.

[0108] For each PRM in a flavor blend or composition, various molecular descriptors are calculated using its molecular structure. The molecular structures are determined by molecular structure diagrams provided by the Chemical Abstracts Service (“CAS”), a division of the American Chemical Society, Columbus, Ohio, USA. These molecular structures can be obtained from the CAS Chemical Registry System database by looking up the index name or CAS number for each PRM. For PRMs not yet listed in the CAS Chemical Registry System database at the time of testing, their structures may be determined using other databases or information sources. For PRMs that may have more than one isomer, the molecular descriptor calculation is performed using the molecular structure of only one of the isomers representing that PRM. The selection of the isomer is determined by the relative extension of the isomer's molecular structure. The isomer representing the PRM is selected from all its isomers because it is the most common isomer of that PRM's molecular structure. The structures of other possible isomers of that PRM are not included in the calculation. The molecular structure of the most common isomer is paired with the concentration of the PRM, where the concentration reflects its abundance in all isomers of the PRM.

[0109] Use a molecular editor or molecular painting software program such as ChemDraw (CambridgeSoft / PerkinElmer Inc., Waltham, Massachusetts, USA) to reproduce the 2D molecular structure representing each PRM. The molecular structure should be represented as a neutral substance (quaternary nitrogen atoms are allowed) without broken segments (e.g., a single structure without counterions). The winMolconn program described below can transform any deprotonated functional groups into a neutral form by adding the appropriate number of hydrogen atoms and discarding counterions.

[0110] For each PRM, molecular drawing software is used to generate files describing the PRM's molecular structure. One or more files describing the PRM's molecular structure are then submitted to the computer software program winMolconn version 1.0.1.3 (Hall Associates Consulting, Quincy, Massachusetts, USA, www.molconn.com) to deliver individual molecular descriptors for each PRM. Therefore, it is the winMolconn software program that specifies the structural symbol representation and the file formats for acceptable options. These options include MACCS SDF format files (i.e., structure data files); or the Simplified Molecular Input Line Entry Specification (i.e., SMILES string structure linear symbol representation), which is typically used in simple text files, generally with a ".smi" or ".txt" file extension. SDF files represent each molecular structure in a multi-line record format, while the syntax for SMILES structures is single-line text without spaces. You can add the structure name or identifier to the SMILES string by including it on the same line after the SMILES string, separated by spaces, for example: C1=CC=CC=C1benz.

[0111] The winMolconn software program is used to generate multiple molecular descriptors for each PRM, which are then output in tabular format. The specific molecular descriptors derived by winMolconn are subsequently used as inputs (i.e., as variables in mathematical equations) for various computer model testing methods to calculate values ​​such as: saturated vapor pressure (VP); boiling point (BP); logarithm of the octanol / water partition coefficient (logP); odor detection threshold (ODT); odor reduction value (MORV); and / or a universal odor reduction value (universal MORV) for each PRM. The molecular descriptor notation used in the model testing method calculations is the same notation reported in the winMolconn program, and their descriptions and definitions are available in the winMolconn files. The following is a general description of how to implement the winMolconn software program and generate the required molecular structure descriptors for each PRM in the composition.

[0112] Calculate molecular structure descriptors using winMolconn:

[0113] 1) Assemble the molecular structure of one or more flavoring ingredients in the form of a MACCS structure-data file (also known as an SDF file or SMILES file).

[0114] 2) Using the winMolconn program version 1.0.1.3 running on a suitable computer, with the above SDF or SMILES file as input, calculate the complete set of molecular descriptors obtained from the program.

[0115] a. For each structure in the input file, winMolconn outputs an ASCII text file, usually separated by spaces, containing the structure identifier in the first column and the corresponding molecular descriptor in the remaining columns.

[0116] 3) Use spreadsheet software or other appropriate techniques to parse the text file into columns. Molecular descriptor tags will be visible in the first row of the resulting table.

[0117] 4) Locate and extract the descriptor column, which is identified by molecular descriptor tags, corresponding to the input required for each model.

[0118] a. Note that the winMolconn molecular descriptor tag is case-sensitive.

[0119] MORV calculation

[0120] 1.) Input the molecular descriptor value determined by the method described above into the following equation:

[0121] MORV=-0.0035+0.8028×(SHCsatu)+2.1673×(xvp7)-1.3507×(c1C1C3d)+0.61496×(c1C1O2)+0.00403×(idc)-0.23286×(nd2).

[0122] The equation relates to the effectiveness of the material in reducing the malodorous 3-mercapto-3-methylhex-1-ol (thiol-based malodor), and in this invention, it is used as a marker for other sulfur-smelling compounds such as hydrogen sulfide and methanethiol.

[0123] 2.) For the purposes of this application, the MORV of the material is the highest MORV value derived from the above equation.

[0124] The purpose of this experiment was to determine whether the odor-reducing composition showed any benefit in reducing the perception of odors from sulfur-containing shampoos.

[0125] Sensory testing methods :

[0126] Thoroughly rinse the hair cluster with water (38°C) to fully wet it (5-10 seconds). Add 0.1g of test product per gram of hair and foam for 20 seconds. After 20 seconds, add water and continue foaming for 30 seconds. Assess the sulfur odor of the hair cluster (SM-1). Rinse the hair cluster thoroughly. Assess the sulfur odor of the hair cluster (SM-2). Gently towel dry any excess water from the hair cluster. Blow-dry the hair cluster at a high temperature until it feels completely dry to the touch. Immediately assess the sulfur odor of the hair cluster (SM-3). Cool the hair cluster for 3-5 minutes (until it feels cool to the touch). Assess the sulfur odor of the hair cluster (SM-4). Combine SM-1, SM-2, SM-3, and SM-4 to obtain the total sulfur odor (TSM) or cumulative sulfur smell.

[0127] In this invention, sulfur odor can be assessed or measured on a scale of 0 (no odor) to 9 (severe odor). A non-limiting example of odor assessment is as follows: an odor assessment scale with a 10-point scale, where the descriptors are: 0 = Odorless / Fragrance-free / Odor present; 1 = Slightly present (I think there is fragrance / odor, uncertain); 2 = Slight to moderate (I detect some odor, but can I identify it?); 3 = Moderately present (slight fragrance / odor); 4 = Moderate to high (medium fragrance / odor); 5 = High; 6 = High to very high; 7 = Very high (strong fragrance / odor); 8 = Extremely high; 9 = Extremely high + extremely strong fragrance / odor.
